Description

Multi-color point recorders Multi-point recorders are used to show the course of the measured values from several measuring points on a common recording strip to record. For this purpose, the individual measuring points are periodically driven by a motor driven changeover switch connected to a measuring mechanism, through which the respective measured value is registered by punctiform markings. In this way point records are created for each measuring point. To distinguish these point writings from each other and the individual To be able to clearly assign measuring points, it is customary to assign a color to each measuring point assign so that z. B. a red dot record for the first measuring point, a green one Point record for the second measuring point etc. is created.

Experience has shown that practically no more is possible to use than six different colors for identification, as there are finer color differences cannot be perceived with certainty either in daylight or in artificial light. The marking of the writing by different colors is therefore not straightforward possible if there are more than six measuring points. It is already known to identify the writings by printing small numbers or the individual Registration points various forms, e.g. B. circular shape, cross shape, star shape or. like. To give. Apart from the associated construction difficulties The ability to distinguish such writings leaves much to be desired, especially when the writings are close together and cross each other.

There is also a multicolor point pen known in which, in addition to monochrome Written such in a predetermined color combination are made to make this additional To be able to assign measuring points. In this known arrangement there is a single control cam arranged, which controls the ink carrier so that alternate with the individual letters Points of the same or different color are recorded. There is one to do with it large, relatively difficult to manufacture control cam required for more than three colors (i.e. six writings) can practically not be carried out.

The principle of defining an assignment through different color combinations To enable records for additional measuring points is also the present one Invention based on an appropriate training required for this Ink carrier control device relates.

In the case of a multi-color dot pen with a switching device synchronous with the measuring device switchable color carrier, the fewer colors contains as measuring points and in which the individual measuring points are monochrome Writings of different colors or multicolored writings in a predetermined combination of colors are assigned, according to the invention, the color carrier switching for the purpose of insertion a color code can be locked periodically.

The invention is based on the previously customary type of multicolor point pen in which several measuring points are assigned different monochrome writing. For the additional measuring points, writings in the same colors are provided, in the several points with a preferably uniform identification color for differentiation of the former can be inserted. This insertion of the identification color is through a periodic locking of the color carrier switching can be achieved, so that no big and complicated. Control discs, as in the above-mentioned known arrangement, will be required. For the applicability of the invention, it is of no importance how the ink carrier is designed in detail, z. B. as a ribbon, ink pad, Color pencil, colored felt or the like. It is also irrelevant whether the registration of the measured values by a drop bracket or by a pressure magnet or other known '' done quietly.

In the case of multi-color point pens that swivel in the usual way have stored ribbon carrier, which is supported by a rotating with the measured value switch Cam is controlled, the invention is thereby particularly simple realize that in addition to the cam, a locking disk driven by a gearbox is arranged, which is used for periodic locking of the ribbon carrier.

The invention is shown schematically on the basis of the drawing Embodiment explained. In the drawing, 1 is the pointer a measuring mechanism 2, which plays under a drop bracket 3 in a known manner and through this at predetermined time intervals for generating a registration point is depressed on a tab, not shown. Between the Pointer 1 and the registration strip are different colored - color ribbons 4 are arranged, which are attached to a pivotably mounted ribbon carrier 5. On the ribbon carrier 5, a lever arm 6 is attached, which rests on a revolving control cam 7. The control cam 7 is provided with a rotating one not shown in the drawing Measuring point switch coupled, the twelve different measuring points one after the other the measuring mechanism 2 switches on. After each switchover of the measuring point, it is carried out in a known manner the drop bracket 3 actuated and the respective measured value as a point on the slowly moving Register strips registered. By the control cam 7, the ribbon carrier 5 pivoted, so that with each registration a different ribbon 4 under the pointer lies. Since six different ribbons 4 are provided, that is, completed. the control cam 7 one full turn after six measuring point switchovers, after which the lever 6 slides on the edge 7 'of the control cam 7 and falls back into the starting position. With this arrangement there would be six different colored dot writings twice arise, of which the one assigned to the first measuring point and the one to the seventh Measuring point has the same color. The writing of the second measuring point would have the same color as the writing of the eighth measuring point, etc. To each to be able to differentiate between the same colored writing of the different measuring points etc. are added periodically in the records of the seventh to twelfth measuring points some registration points in an identification color, e.g. B. Red, inserted. It turned out to be proved expedient, three points each in the identification color and seven points in the associated registration color to be provided.

To achieve this, there is a locking disk on the shaft of the control cam 7 8 arranged, which is provided with three teeth 8 'and recesses 8 ". This locking disc 8 is through a gearbox, not shown, for. B. a Maltese cross gear Od. Like., rotated intermittently and leads to twenty revolutions of the control cam 7 one full turn. Through the teeth 8 'on which the lever 6 to rest comes, the ribbon carrier 5 is locked so that as long as one of the teeth 8 'in Working position is, all registrations in one color, namely the identification color, take place. So while the control cam executes twenty revolutions, which is ten registrations corresponds to each of the twelve measuring points, the measured values of the seventh to twelfth are Measuring point registered three times in the same color and seven times in different colors, while the values of the first to sixth 11eßstelle only monochrome in the six different colors can be applied. Two would not be that way distinguishable writings in the identification color are created, but what can be done if necessary z. B. Avoid by an additional switching process and changing the color code " can.

PATENT CLAIMS: 1. Multi-color point pen with one through one Switching device synchronous with the measuring point switchover switchable color carrier, which contains fewer colors than there are measuring points and in which the individual Measuring points single-colored records of different colors or multicolored records are assigned in a predetermined color combination, characterized in that the color carrier switching can be locked periodically for the purpose of inserting an identification color is. 2.
